The TimedLockable requirements describe the characteristics of types that provide timed exclusive blocking semantics for execution agents (threads, processes, tasks).
For type L to be TimedLockable, given.
rel_time, a value of a specialization of std::chrono::duration, and abs_time, a value of a specialization of std::chrono::time_point, the following conditions have to be satisfied for an object m of type L:
| Expression | Effects | Return value |
|---|---|---|
m.try_lock_for(rel_time) | Blocks for the provided duration rel_time or until a lock on m is acquired. |
true if the lock was acquired, false otherwise. |
m.try_lock_until(abs_time) | Blocks until the provided time point abs_time is reached or a lock on m is acquired. |
true if the lock was acquired, false otherwise. |
The try_lock_for and try_lock_until member functions obtain a non-shared lock on m on succcess.
